For the pork, combine all ingredients in a zip-top plastic bag, squeezing well to distribute garlic and ginger. Refrigerate for several hours or overnight. Preheat grill and when hot, grill pork over hottest part of the grill, turning every 2 to 3 minutes. Move to cooler part of grill, cover grill and cook an additional 3 minutes, or until internal temperature reaches 145 degrees for medium or 160 degrees for well done. Alternately, the pork tenderloins can be roasted in a 325-degree oven for 45 minutes. For the salsa, combine all ingredients in a medium bowl. Cover and refrigerate until ready to serve. Slice the pork on the diagonal and top each serving with some of the salsa.
